CAR END FRAME. y

Specification of Letters Patent.

y Patented Mar, 4, 1913.

To all whom it may concern: p

Be it known that I, HARRY M. PFLAGER,

acitizen of' the 'United States, residing at St. Louis, Missouri, have invented a. certain newand useful Improvement in Car End Frames, of which the followingfis a full,

clear, and exact description, such as willvtaken n the line,4-f4 f Fig. 1. Fig.'5 is a horizontal sectiontaken approximately on the line 5-5 -of Fig. 1.

This invent-ion relates generally to rail way car construction and more particularly to cast metal end frames for cars of the type disclosed in Patent' #917,716, issued April 6, 1909, and #929,705, issued August 3, 1909.

One of the most important features in the construction of the present forms of railway cars, and particularly those cars utilized fortransporting passengers, is the reinforcing of the ends ofthe cars so as to providean exceptionally strong, rigid constructlon which will eifect-ually resist crushing stresses -delivered to the ends of the cars, conse quently overcoming the tendency of the cars lto telescope in case of collisions, and affording the' greatest possible degree of safety to the occupants of the cars.

My improvement contemplates va com. paratively lightweight, strong and durable one-piece cast Vmetal structure which is formed and braced so as to effectually resist end shocks and crushing stresses 'imparted to the ends of the car, therebyproviding a construction which is anti-telescopic in effect.

Theprincipal objects of my present invention are to generally improve the construction of the cast metal end frames disclosed in the patents above referred to, to form braces on the end frame and fix said braces to the underframe in such a manner as to rigidly maintain said end frame in an upright position, and further to arrange and dispose the 4various uprights, cross pieces and braces formingthe end frame so l Application tiled April 15, 1 912. Serial No. 690,969.

ig. 2 is a'plan view of- .as to utilize to the reatest possible advantage the strength o the material of which said parts are formed in resisting end shocks further to construct a lone-piece cast metal end frame particularly adapted for use on blind end cars.

To the above purposes my invention consists in certain'novel features of constructlon and arrangement' ofy parts hereinafter more fully described and claimed.

Referring by numerals to the accom anying drawings; 1 designates the under rame and A2 the end member or buiing sill thereof, which parts are preferably cast integral.

My improved end frame as shown indi- -and crushing stresses 'due to collisions and cates a central pair of upright members 3 which perform' the-functionof. door posts, a pair of side members 4 which perform the function of corner postsand a pair of intermediate upright members or posts 5. The outer pair of upri ht members 4 or the corner posts are pre erably Z-shaped in cross 1 section and formed integral with the outer edges of the transversely disposed flanges of said Z-shaped members are rearwardly projecting flanges 4a. Formed' integral with the lower portion of these uprights or cors ner posts' are brackets 6, the Webs of which are continuations of the rearwardly projecting flanges 5, and the lower rear ends of said' brackets bea-i` directly against shoulders or lugs 7 formed on t-he side pieces of the underframe 1. 'lhefhorizontallyl disposedv base flanges 6"i of the brackets 6 restdirectly upon t-he underframe'and these parts are ixed to one another by means of rivets 8 or like fastening devices; The intermediate posts or uprights 5 are preferably channel-shaped in cross section and the lower ends of said intermediate uprightsor posts are connected to the lower portions of the corner posts by horizontally disposed plates 9 which rest directly upon the buing sill and being fixed thereto by means of rivets or like fastening devices 9a. `The inner pair of uprights 3 Which perform the function of doo-r posts are considerably -Wider thanV the posts 4 and 5 and said door posts are substantially of `I-beam shape in cross section. A. pair of the outer iianges and a pair of the inner ianges of eachA of these posts' gradually said osts so'that saidupper ends are su taper in width toward the upper ends 'gf stantially Z-shaped4 in cross section, Wh` l1 arrangement materially reduces the weight without sacrificing strength.

The lower portions of the door posts 3 are connected to the lower portions of the intermediate posts 5 by comparatively wide horizontally disposed plates 10 whichrest directly on top4 of the butting sill and being fixed thereto by means of rivets orv like fastening devices 10a. Formed integral with the front edges of theplates 10 and the lower ends of the posts 3 are depending plates 11 which bear directly .against the front face of the butiing sill and being fixed thereto by means of rivets 11a or like fastening devices. The lower portions of the uprights 3 are united by a horizontallyT disposed plate 12 which rests upon and isrigidly fixed to the top of the buliing sill 2, and

said plate performs the function ofathreshold plate for the door frame. readily understood that the posts or uprights 3, 4 and 5 may be of any desired cross sectional shape. v

By the'construction just described the lower portion of the end. frame is rigidly fixed to the under-frame and all end shocks or crushing stresses imparted to said end frame are eifectually resisted by the. brackets 6 which perform the function of braces at the sides of the end frame and by piroviding the depending plates 11 and the shouldersf( against which the rear ends of the brackets 6 engage all shearing strains are removed from the various rivets or like fastening devices utilizedin rigidly fixing the end frame'to the underframe.

Horizontally disposed rails`13 which are preferably of inverted L-shape in cross section are formed integral with and unite the upper ends of the posts 4 and 5 with the upper portions of the posts or uprights 3, and formed integral with and uniting the upper portions of the posts or uprights 3 is a rail l-l which is of inverted L-shape in cro-ss section and the horizontal iiange of which performs the function of a lintel for the door frame.

Formed integral with the rear edges of the' rails 13 and let is a vertically disposed plate 15 which is perforated, as designated by 1Ga to accommodate the train bell cords,

and formed integral with this plate 15 be-v tween the posts 3 and 5 are vertically disposed plates 16 that serve as supports for the lower ends of the ventilator frames.;I The posts or uprights 3 extend above the rails 13 and 14 and formed integral with the upper ends of said posts or uprights 3 are horizontally disposed brackets 17 the outer ends of which project slightly beyond the plates 16, and these bracketsl serve as supports for parts of the car roof and' car hood. Horizontally disposed rails 18 arel formed integral with the po-sts 3, 4 and 5 and an elevation which is substantially in the same plane with the belt rail of the car body.

ing the same so as to bear directly upon the underframe an exceptionally strong, rigid antl-telescopmg construction 1s provided which in service affords a maximum degree of safety lto the occupants of the car during collisions.

The central pair of posts or upriglits 3 which perform the function of door posts are made substantially wider than the remaining posts, thereby providing an exceptionally strong, reinforced construction at the center of the end frame or at the sides of the door opening.

It'will be readily understood that minor changes in the size, form and construct-ion of the various parts of my improved end frame can be made and substituted for those herein shown and described without departing from the spiritof my invention, the scope of which is set forth in the appended claims.

I claim:
